Abstract
The article discusses the possibilities of improving the physico-mechanical properties of ceramic bricks based on low-grade loams. The features of using low-grade clays, which are usually not suitable for the production of high-quality bricks due to high humidity, low strength and other unfavorable characteristics, have been studied. The methods of improving these properties through the addition of various mineral additives, modification of the composition of the clay mass and changes in the technological processes of firing are considered. Possible ways of increasing the strength, water and frost resistance, as well as improving the thermal insulation characteristics of ceramic bricks are analyzed. The description of experimental studies includes a variety of ways to influence the structure and composition of clay, which helps to increase strength, improve density and other mechanical properties of the finished brick. The methods of increasing environmental safety and economic efficiency of brick production based on low-grade loams are being investigated. In addition, aspects of environmental safety and the economic feasibility of using low-grade raw materials are considered. The results obtained confirm that with the right processing technology and the addition of modifying components, it is possible to significantly improve the properties of ceramic bricks, which opens up new opportunities for the efficient use of local natural resources and reducing the cost of building materials.
